We synthesized pure-red-emitting CsPbI3 nanoplatelets demonstrating high stability, quantum yields, and horizontally oriented transition dipole moment.

We demonstrate that 2D materials sitting on hydrogels are nearly strain-free.  

Together with the deMello group, we present low-​cost disposable electrochemical sensors for quantitative diagnostic assays toward the point of need.    

We developed bending-insensitive ultraflexible monochromatic light source powered by integrated solar cells.

Together with the deMello group, we present low-cost electrochemical bioassays fabricated on paper using laser-graphenized electrodes.   

We synthesized new asymmetric Au(III) organometallic OLED molecules demonstrating record-breaking effciencies.   

Yinyin's collaborative work with the Leroux group uses machine learning to explore a new series of polymer dyes with emission covering entire chromaticity.  

Leonard's collaborative work with the deMello group demonstrates a smartphone-based lateral flow assays for rapid testing.

Our multiscale analysis and photophysical characterization reveal that the transition dipole moment orientation in perovskite nanoplatelet solids is largely confinement-tunable.
